With an SSD, if you're concerned about someone with a lot of resources trying to recover data, erasing by overwriting is actually not enough, because the SSD keeps some blocks in reserve to manage wear leveling, and overwriting the data that the computer sees doesn't overwrite those blocks, they can be recovered by someone who swaps out the firmware. Multiple passes of random data is the paranoid overkill option, but overwriting just once with zeros is just as good unless you're using a 1980s hard disk and facing an adversary with considerable electronics equipment (and even then the recovery possibilities were haphazard). DBAN writes multiple passes of random data, which is unnecessarily slow and causes unnecessary wear on the disk (that's mostly relevant for SSD). If by work you mean “does it erase the disk”, then yes, sure, it erases the disk, that's exactly what it's for.
